TRUCK SIDE FRAME'.

l Speccation of Letters Patent.

Patented oct. e, 190s.

Application led Felaruary 19, 1908.. 'Serial No. 416,652.

-,' of--Pennsylva.nia, have invented a new and useful'Truol; Side Frame, of which the folflowingis a f ulhclear, and 'exact description,

f refe'renoebeing had Ito. the accompanying IlavViIgS, forming part of thisspciiieation, in ijihich- Figure 1' is a side elevation, showing one form of my. improved side frame; Fig. 2 is". w an enlarged cross section ofthe journal box 15' .fof the frame; and Figv '5 'is a side elevation por-tiom Fig-v is an enlarged longitudinal detail section of the top portion of the journal box; Fig. 4 is a central cross sect-ion out' the use'of 4rivets or bolts.

' My inventionrelates to the class of truck side-frames, and .is designed .to provide a simple, cheap and strong structure,'in whichv Wrought or rolled metal tension member is. secured'to a 'cast compression member with* Itis also de-l 'signed'to 'provide journal boxes formed 'as a `part -ofrthesame casting with the compress1 on member.

V g v, Inthe drawings,Qrepresents the cast steel compressionmember ofa truckLslde frame,

5 formi-ng the-upper-aroh bari oreqivalent thereof. This member. is preferably provided wthcentral frame extension members I' 33,'.coi1nectd .bythelvver member 4, which preferably CaStaboHtfthe central portion "of the lower arch-bar/ and-'the tie bar6. j

The end 'portions of theV cast-member 24 are flowed'or cast. about. and. inolose the bent or .hookedend portions of the lovver arch bar onte'n'sionl member,- and the journal boxes' 8' 8, aref'preferably formed'of cast steeland are cast integral Withfthe compression mem-I ff Aber and the parts 3-ar`1 d 4 =.-1The ends '9 of the -t-ie 'bar .6 lare preferably' perforated or `recessed and are inclosed Within the, cast metal 10 at'thelowersideof-the journal boxvl ..45l

In the form' shoWn,fthe lower frame memlber his provided l'with integral s ide'wise -ex-4 spring planks 12; i v"1Q i `these molds-aire formed to simulta- 0. which are bolted-they'.

lInfor 1.4 gthe si'de'rframe, moldsy fare placedlaloA 't thenol portions 'and :middle- -portions of 't effloiierarch.` bar: and tie bar, V lwhich are of rolledl-or wroughtmetal,

' n eously shape the compression member, cen

tral frame member and journal boxes, and

secure these'parts to the end portions of the lowerareh bar and the tie bar by the act of casting.

In Fig. 5,- I show a form similar'to the other iigur'esexcept'that the journal box 13 is of the ordinary type, and is secured between the end port-ion 14 of the lower t-ie bar and theen'd portion .15 of the compression member which 1s cast about the hooked en d portion a of the tension member. In this case, thel ordinary v'securing .bolts are employedA as shown at 16, and the'end portion of thecOmpression member may be shaped to 'conform to any desirable type of box; B y

fio

or other securing means. `The tension members are of Wrought metal, which gives high tensile strength, vvhil'e` the compression member isofcast steel, which presents great resistance. to compression.v Inthe act of forming -the cast member, the other parts o f the frame are secured and strengthened, While `the cast part is given its desired shape. The "centereast portion is formed vas an integral Athe lovver'arch'ba'r and tie bar.

The form ,andV arrangement of the side .frame may be varied.4 The central frame .part V'of the upper arch'bar, and at the same time -is secured to'- the vintermediate parts of' 'casting maybe formed separately from the upper archzbar or frame member, the' casting securing the ends. of the archbarS-inay -be 'I formed separatefrom the joiirnalboxes, if desired', so that separate journal boxes may befafpplied,and many other' changes may be n made Without departing' from "my invention.

l.; A 'triiolrsideframe having a .sfide frame member vwith itsen'd ortions inclosed by another-'side frame mem )er cast about the parts,

substantially lasdescribed.

cast-'franiefmember Withfits'lends formed of A-metal flotiied about' ogllfwer `framemi embel'nV substantially as'describedg.l 3.' A truckframe 'having a'compres:

sion member formed as a steel casting and a tension member consisting of Wrought metal, the steel casting being flowed about arch bar member with an intermediate integral downward extension and a `lower Wrought metal bar having its ends secured to the cast arch bar member, substantially as described.

A truck side trame having a cast compression member with an intermediate frame extension formed of metal flowed about the lower arch bar and the tie bar, substantially as described.

(3. A truck side frame having a side frame compression member consisting of a. steel cast-ing with the journal. boxes cast integrally therewith, and a Wrought metal tension niember secured to the compression member, substantially as described.

7. A truck side frame having a side frame member consisting of a steel casting with the journal boxes cast integrally therewith. and a lower wrought metal member having its I ends secured by casting portions of thc upper member to them, substantially as described.

8. A truck side trame having a side frame member consisting of a steel casting with the journal boxes cast integrally therewith, and

a lower tie bar having its ends secured -by fiowing the metal of the journal box portions about them, substantially as described.

9. A truck side frame having a cast upper arch bar member with an integral intermediate downward extension flowed about the intermediate portion of a lower wrought metal member, substantially as described.

10. A truck side frame having a cast upper arch bar member with an integral intermediate downward extension flowed about the intermediate portion of a lower wrought metal member, the cast extension having side anges for securing the spring plank, substantially as described.

11. A truckjside frame having an upper cast frame member and a lower wrought metal member having bent or hooked ends secured to the upper cast member by flowing the metal about these bent ends, substantially as described.

12. A truck side frame having a cast compression lnembcr, a wrought metal lower arch bar, and a wrought metal tie bar, the end portions of the cast member being owed about the end portions of the wrought arch bar member, substantially as described.

In testimony whereof, I have hereunto set my hand.
